Abstract :
Background
Good knowledge of the expected normal lumen size at a given coronary artery site is the most important first step towards developing a quantitative estimation of coronary artery disease severity. Size of the coronary artery is the most important predictor of outcome after percutaneous coronary interventions (PCI) and coronary artery bypass graft surgery (CABG).
Aim
To find out the normal dimensions of the coronary artery segments in Indians without coronary artery disease by using quantitative coronary angiography and also to compare the dimensions in Indians with various studies.
Material and method
Out of 1258 patients who have undergone coronary angiography, 62 patients (42 male and 20 female)with entirely normal coronary angiogram were selected in the study.Patients with history of diabetes mellitus, hypertension, renal disease, valvular heart disease, cardiomyopathy were excluded.
Results
Diameter of the coronary vessels in males and females when taken together the left main was larger in size followed by proximal LAD, proximal RCA & proximal LCX respectively (4.05 ± 0.14 mm, 3.15 ± 0.14 mm, 2.84 ± 0.84 mm, 2.95 ± 0.91 mm).LAD measurement was 3.15±0.14, 2.95±0.10,2.41±0.27mm at proximal LAD, mid LAD & distal LAD. LCX measurement was2.95±0.91, 2.65±0.56 mm at proximal & distal LCX. RCA measured as 2.84±0.84, 2.50±0.5mm & 2.15±0.56 mm at proximal, mid & distal RCA.
When the proximal vessel diameters were indexed to body surface area there wassignificant statistical difference between male and female (P value < 0.05).Mean diameters of proximal coronary segments indexed to body surface area of our study when compared to Caucasians (Birmingham study) showed that there was no statistical significant difference (p value > 0.05).
Conclusion
Dimensions of proximal coronary segments when indexed to body surface area have statistically significant difference among sex distribution in our population.We found that coronary arteries when indexed to body surface area was not statistically different as compared to western population Caucasians.
